I am working on a pen plotter.. wbu?

lilac needle
#

right now I want to try remake the gravity gloves from half life alyx

#

rn I'm trying to brainstorm some practical things to do tbh. Might try build a little robot arm and mess around with servos! I do know I wanna try design my own pcbs too!! everything about hardware really fascinates me. Guess I just don't know what to do with all this interest lol, but the gravity gloves and robot arm seem really awesome to me. Might be cool to get like a hand tracker match movements to a little robot arm. Seems really complex though

#

I barely know how to use resistors properly lmao, I'm a completeeee noob to circuits so trying to get the basics rn

Guys i wanna start coding and i dont know how can i start and am confused about it! Please someone provide some tips for starting .

gloomy lily
#

data analysis maybe

lilac needle
#

my other tip would be, look at some examples of what people have coded up. If you find something interesting, put it in a list of "inspo projects". Once you sort of are comfortable enough to program, try break down those cool projects into little tasks you can do.

EG, you really like a videogame; lets say uhhh, undertale!

okay, break it down into one cool feature you'd want to try make yourself; ie, a character moving around.

now break it down even more; ie, a square on a screen moving

now break it down even MORE; ie, just having something show up on a screen.

When you achieve something, by looking stuff up, and researching on how people have done it, move forward to the nest broken down task and try learn how to do it.

This is the method I use for when I want to try self learn something

#

The key is to have a project/goal that ACTUALLY excites you.

#

So for me, it would be making some sort of interactive game. Hence the examples of coding movement to happen when someone presses a button etc.

#

Anyway, if you really don't know a thing, just dive straight into some online free course and COMMIT to it. Don't compare different courses. Just pick a direction and move. Once you learn more, you'll be able to redirect yourself and really ask "okay, what do I want to learn??"

#

anyway I reccomend you dive in with a coding language like C++. If thats too difficult and you're having a hard time, then just go the Python route

#

trying C++ first could really benefit you. But also, the language you learn also depends on what you want to do with your coding skills etc, so just try research on what other people you look up to have done etc.

#

Sorry for the ramble lol, I hope its useful at least

# lilac needle Sorry for the ramble lol, I hope its useful at least

The above things which you told and the course you provided will really help me a lot. I was really confused on how to start but now i will be able to start and make a clear decision on what i want to do afterwards. Thanks a lot for taking time and explaining these things to me. I really appreciate it and thanks again!

Hello //so I've been using endevour Linux form last 5-6 months and from the start there were mirror issue and I couldny download or update anything I've tried fixing it countless times from chatgpt help cuz I know nothing about stuffs like that so yea chatgpt gave me commands to change to different mirror and also did some reflector thingy . I've tried to troubleshoot the issue sooo mnahyyy timesss it drives me nutsss just thinking about retrying it. I've a vague idea of why it might happen cuz when I was downloadg endevour iso the network was bad and download interrupted so I've tried redownloadig iso of arch Linux๐ŸŒ cleanly without any interruption ....sooo the main concern is I m a studio noob in terms of system trouble shoot and if I run in some arch problem I'm cooked .so if anyone have some advice and suggestion please tell me ๐Ÿ˜ญ

#

pacman -S i think

and i dont get what you said in the second part with the redownloading iso

# gloomy lily pacman -S i think

When I do sudo syuu thingy to upgrade whole system it show url 404 error and after I change mirror and tried a lottt it still showed url 404 error (which apparently is broken mirror but I changed to every good mirror ) but it started downloading the apps but it got stuck again in several other things wait lemme do it again and show u reasults

hey guys, anyone here have tried Dell latitude laptops?

currently eyeing for dell latitude 5420

as an upgrade from my current T470

tho im not sure about the overall build quality and linux compatibility
especially the keyboard and trackpoint (which i really love from what thinkpad offers)

refurbished thinkpads are still expensive in here, at same price i can get higher spec from refurbished dell latitude

gloomy lily
#

i do that a lot

#

i spend like 2 hours reading the subreddit and figured that i didnt understand shit

#

so im hoping that i kinda get a better understanding of what i want from IEMs

#

and then when i do, i will buy new ones for around 100โ‚ฌ :)

iโ€™ve been using a latitude 5480 since before i was into thinkpads or linux or anything because i was able to get one free and i donโ€™t really have any issues with it, cant compare it that much because i dont have experience with higher end laptops but its good and sturdy, it can heat up and get noisy but what can you expect from a laptop like this and i have not had any compatibility issues daily driving it with arch

#

been thinking about upgrading for uni soon but not really sure what iโ€™d get

#

frameworks are pretty enticing

limber sentinel
#

if so, then id recommend the ipad, the responsiveness and app support for the apple ecosystem for education is too good to pass up on when youre trying to have a "it just works" experience when youre at school

#

that being said, i own a book go 7 for reading books in bed and while i love the page turn buttons, fumbling around w android e-ink displays hasnt been my favourite

and plus i really prefer the boox go 10.3 design and screen benefits over the ipad

hi raul, there's a beginner's guide on NX product section of the siemens support centre portal, under "getting started". get your institution to make you an account if you don't have one already, it's a useful thing to have. also i haven't used NX but in star-ccm+ there's built-in documentation if you hit f1 (or help>help in the menu), it might be similar for NX

Have you tried reindexing? It seems there's a history of this bug happening with the software

How do I get my Windows 11 indexing to work properly - Microsoft Q&A

# amber oriole Sir, I am using the Powertoy app

well powertoys is a microsoft product, so obviously it integrates with windows features, and search indexing is a feature that allows you to search for any files on your pc and not just apps

search indexing also speeds up the search process

Any gods of x86-64 in here?
I'm trying to save a 128 byte buffer on the stack and access it after a recursive call. I keep getting bus errors, I think I'm misunderstanding something fundamental.

#

Any programmers here? Super road blocked on a Data Structures Proj

grim vale
#

what's the question

rich remnant
#

Making Linked Lists but idk what to do or how to just keep the thing as null before I assign it with a link

#

like I made a Node class which ig is like chain links and then the Linked List class to make a list using the Nodes connected to eachother

covert phoenix
#

you can make a dummy node

grim vale
#

You got some source & question you can show?

covert phoenix
#

or have a 'list' class that will keep a pointer to the first node

rich remnant
#

Not really a source question but its mapped off of Micheal Main - Data Structures and other Objects Using Java

#

My prof really likes working off of txtbook

#

hm

#

Idk if Im allowed to do that with making a list that points to Node

#

Im prolly describing this weird -_-

covert phoenix
#

hmm, i mean

#

you gotta point at the list somehow

#

so you just hold a pointer to the first node?

rich remnant
#

I have like an instance var that points to the head

#

of list

covert phoenix
#

mhm

rich remnant
#

that node is linked to next node

#

etc...

covert phoenix
#

yup

rich remnant
#

until final node which is linked to nothing

#

I believe im only allowed to go through it by following the links of the links

covert phoenix
#

in most basic form yeah

rich remnant
#

Or Im over complicating this

#

prolly that one

covert phoenix
#

okay, so whats the problem again

rich remnant
#

But when I generate a node there is no other node to link it to

#

so its just node

#

do I just create a method to link it to a new node?

#

sry I meant the link is just null

covert phoenix
#

yeah

rich remnant
#

at least thats the default I have

#

Ah

#

Idk why Im making this so frustrating lol

#

Ill try, thx @covert phoenix !

covert phoenix
#

im not sure how textbook that will be, but it should definitely work

grim vale
#

i googled the text book

#

trying to find the page he's on

rich remnant
#

pg 177

grim vale
#

My guess is around 180~?

rich remnant
#

Theres like a section of just linked lists

#

Theres a section on 178 that talks about the null reference but im kinda confused

rustic mesa
#

I dont quite understand what you are confused about. Is it the case with a list of only one entry?

grim vale
#

which edition of the book are you on

covert phoenix
#

the general idea is to have a method for it

rich remnant
#

@rustic mesa Kind of yeah

rustic mesa
#

In the case of one entry the "link" should just not point to anything

#

Null, 0, -1 or point to itself

#

And save the pointer to this node somewhere, because when you add to the list you want to do the following

#
  • Create a new node which points to nothing
  • Enter the node you saved (first node)
  • Traverse through the links node by node until you find the last one which has a null pointer
  • Change the null pointer to point at the new node
rich remnant
#

For the 3rd point would I just make a loop that iterates through

#

Node link = Node ....

rustic mesa
#

Sure, if you want to be a good CS student you should do it recursively :p

rich remnant
#

Node next = link.getLink()

#

@rustic mesa Hmmm, so just calling Node again in the loop?

rustic mesa
#

Just think that you only have access to the very first node. There is no way you can jump in the middle of the list or whatever

rich remnant
#

So Im going to have to go through the links

#

recusrively?

rustic mesa
#

yeah

rich remnant
#

Gotcha

rustic mesa
#

You dont have to do it recursively, but that's the preferred way

#

While loop also works

grim vale
#

I would recommend get the basics of it done first

rustic mesa
#

especially in java and high languages like that

grim vale
#

then if you can, do it recursively

#

but getting it working first is the important step :P

rich remnant
#

Ok, cuz im not super good at recursive I always get mad errors

rustic mesa
#

Go for a while loop then

grim vale
#

yeah

rustic mesa
#

while(node.pointer != nil):
node = node.pointer

rich remnant
#

So something of while (var holding link)!= null?

#

ah

grim vale
#

neat while loop, get it functional, then go for recursive because, why not, challenge yourself

rich remnant
#

Ok

#

thx so much!

Depends how much of the instruction set you need help with though

#

Just wondering if there is a smart way to save local variables larger than 8 bytes on the stack.
Atm I'm just pushing it 8 bytes at the time

#

But it seems like it's the only way

regal quartz
#

I believe that's generally the only option for dealing with larger values yeah

#

I would say try writing something that does that in c and disassemble it to see how your c compiler does it

#

But all primitive types are 64 bits or less

#

been doing it for a couple of years know but only recently began programming in an academic setting

#

typically jsut did it for personal projects or data science in labs

thorny rock
rich remnant
#

yee ^^

solid patio
#

I'd focus on learning programming principles and fundamentals, maybe just start a random C, C++ or Java programming course

#

(there's many very good free ones on there, udemy or something like that)

twin fox
#

I'm already pretty familiar with programming fundamentals. I use JS, Go, and Python everyday for my day job

solid patio
twin fox
#

But I've been wanting to dive into a lower-language and have been bashing my head between C and C++

solid patio
#

makes things easier

thorny rock

C++ is the hardest language around, but fun

hybrid ledge
#

then c++ is pretty similar to js

#

both are POO

solid patio
#

thx!

solid patio
#

"typo"

thorny rock
#

nah, pointers, vectors, deconstructors, memory management

twin fox
solid patio
thorny rock
#

I'd start with C

twin fox
#

I've only ever read that C++ is complete garbage

solid patio
twin fox
#

Java, too hahahah

hybrid ledge
thorny rock
#

C++ is omnitool or swiss army knife of programming languages

#

it has everything

#

go with C, fun language

#

especially memory allocation, pointers and references

#

and moving bits around

#

plus it is simpler than C++ without many unnecessary things like namespaces, templates and other bollocks

#

and you can program Arduino and embedded as a hobby!

twin fox
#

very true. and it leaves a smaller footprint and quite portable

solid patio
#

i guess you'll be fine either way, but I'd probably take @thorny rock advice

thorny rock
#

not really a subset, they are compatible to some point but sometimes code from .c won't work in .cpp

twin fox
#

indeed. c++ is more like c with stilts (classes)

thorny rock
#

oh and with C you can easily learn and grasp all of those basic data structures like nodes, linked lists and dynamic arrays, because you need to code them from scratch with pointers

twin fox
#

C++ has Vectors ๐Ÿ˜ญ

hybrid ledge
twin fox
#

i talked to a friend about this, and he said, for my purposes, if i need anything more than python that c++ would do the trick because, as janas said, it's a swiss army knife and, unlike C, strings are well handled, which is a PITA in C

thorny rock
#

't have string type, you can only create array of characters and you need also to create functions that will allow you to handle them

#

and i don't know if C can operate on Unicode

#

If you want to learn C in the future then I recommend you reading "The C programming language" by Kernighan and Richie, this book is a Bible of C

twin fox
#

isn't fscanf unsafe?

regal quartz
#

For specific cases sure

twin fox
#

fscanf seems like it works for a file with one or two lines. but what about a big file of strings?

thorny rock
#

and sprintf

#

malloc, pointers and a bit of creativity

twin fox
# 
snprintf(msg, 1024, "Hello, %s", "world");
printf("%s\n", msg);
free(msg);```
thorny rock
#

that's some complicated way to write hello world

twin fox
#

just to concat char arrays

thorny rock
#

oh

#

and the other thing with C

#

and C++

#

learning what all of the error communicates mean

#

this might be mind boggling if you are used to Python / Java errors

#

most of error messages you get in C/C++ might not get you anywhere

#

they can only lead you to depression

twin fox
#

how often do you use gdb?

sorry I did not want to answer to this sentence !

crimson tapir

the code i put was

In python, the string are written with quotation marks, so if you forget them, he will think it is a variable

#

Oh

crimson tapir

isnt it right, tho?

vivid rune

the int() function convert what is inside into an integer

crimson tapir

You just have to remember that the int function is used to convert something that looks like a number into an integer.
It can convert binary value into decimal (or other bases)
It can convert a string that contains only numbers and whitespace into an actual integer.
It can convert a float or other number's type into an integer.

I wouldn't be afraid to learn other languages, in my opinion what's difficult is just learning new features, so if you know a couple languages that cover most features in current programming languages it's pretty easy to pick up a new one

e.g. if you know say c, python, and java many other languages should be easy to learn

why do people prefer LINUX for coding?

twin fox
#

Linux is just an environment. You can use Windows, Linux, or MacOS for development.

#

But, if you're exclusively programming software for Linux, then it makes sense to use Linux

idle dew
# idle dew why do people prefer LINUX for coding?

Either because one they are being cheap or two because Linux is less OSy as in windows is made for even a chimpanzee to understand where as Linux is a bit more of a barebones OS, so things run smoother / faster on Linux.

Does anyone have any experience with building Maps in JavaScript?

#

I was going to use JSON arrays, but it got pretty messy due to me knowing literally nothing about JSON

#

and I was recommended to use maps

#

For reference, my arrays look like this

# 
{
    "Apple Tree": [
        "apfelbaum",
        "apple tree",
        "manzano"
    ],
    "Ball Cactus": [
        "kugelkaktus",
        "ball cactus",
        "cactus bola"
    ],
    "Pumpkin": [
        "kรผrbis",
        "calabaza",
        "pumpkin"
    ],
}
#

I was previously going to make a for loop to check each array

#

so if the message cotains kรผrbis, calabaza or pumpkin then the tree has to be a Pumpkin

#

and it iterated through each array

vapid cloud
grim vale
#

yes

#

ive been working on a college project all night

#

and haven't looked at it

idle dew
#

im not a Javascript fan, but I think its the same concept in c++

#

let myMap = new Map() let keyString = 'a string' let keyObj = {} let keyFunc = function() {} // setting the values myMap.set(keyString, "value associated with 'a string'") myMap.set(keyObj, 'value associated with keyObj') myMap.set(keyFunc, 'value associated with keyFunc') myMap.size // 3 // getting the values myMap.get(keyString) // "value associated with 'a string'" myMap.get(keyObj) // "value associated with keyObj" myMap.get(keyFunc) // "value associated with keyFunc" myMap.get('a string') // "value associated with 'a string'" // because keyString === 'a string' myMap.get({}) // undefined, because keyObj !== {} myMap.get(function() {}) // undefined, because keyFunc !== function () {}

vapid cloud
#

Its a bit different

idle dew
#

u can use myMap.set(key,value)

vapid cloud
#

in Java you have 2 kind of maps

#

and 2 Lists

#

I recommend using LinkedList for Jessica

#

then the functions are the same as C

#

add, remove, contain, ...

grim vale
#

yeah someone had told me about Maps, it's why i mentioned it originally

#

since, I hadn't heard of them before

#

was hoping someone could teach me

rose plover
#

sorry edited, map is not optimal since it returns an array, forEach just loops through the list

unknown.png
grim vale
#

I was told Map would be nice due to it storing it all in memory & only running the array once

#

since, I'm doing it for eveyr tree & language in the Forest app

#

which is 73~ trees and 14 languages

rose plover
# grim vale was hoping someone could teach me

so basically, when you have a list, for example x=[1,2,3,4,5]

map allows you to apply a lambda function to each element of the list and returns the modified list, so
x.map((element) => element +1)
would return [2,3,4,5,6]

in your case you just want to loop through the tree list so a forEach would be recommended

grim vale
#

yeah my originally plan

#

was a foreach loop

#

but then someone told me about maps

#

and now we're back to foreach owoYay

rose plover
#

the map function would be useful if you have a list of strings, and you want to map each string to a tree, then map would be ok since it retunrs a new list with the belonging tree

grim vale
#

well it's 73 arrays with 14 strings per array

#

but if foreach works better

#

then I'll just use that

rose plover
#

i mean, the screenshot i attached would do it for just one string, so if you have multiple strings, a map would be ok to map each string to the belonging tree

and this map funcion on the strings would contain something like the code i sent, to find the right tree

#

added the external map, i hope it's more clear now ๐Ÿ™‚

Do you recommend learning it? honestly I kinda into C++ but i know if taking all the way into learning it would be worthy

#

I mean, theres no chance that im gonna see c++ in my job but i read that is pretty damn awesome in competitive programming

idle dew
#

I only like it in problem solving, like using data structures, understanding them deeply, STL, and especially algo

#

exactly

#

in next week I'll be learning JS

elder trail
idle dew
#

I wanna jump into web development field

elder trail
#

#

I hate everything about designing stuff xD

elder trail
#

Thats the part i like tho most xD

#

we r lowkey yingyang

idle dew
#

so basically I think C++ is the easiest PL

#

you can go for it, it had a huge impact on me mentally, and logically

elder trail
#

In fact i was following codebeauty's 10 hr C++ course

idle dew
#

you only need the ultimate-basics to start competitive programming, then along with solving problem you will face new things that would force you to learn

#

so you do not need a 10h course, you more likely to get bored

#

start with something simple like cin cout and loops, then start solving easy problem on codeforces

elder trail
idle dew
#

if you solved one problem then you should be ready to go, once you face something new you can ask me or start searching for a specific thing

elder trail
#

Fun fact: if u know formatting in Python, u basically know how to concatenate and read input in C

Best place to start then is the free course from Harvard through edX. CS50. It's entirely free, and you submit assignments and they are graded automatically.

You watch the lectures, do the problem sets and labs, and the project and you will be well on your way. It will take time, and it will be difficult but if you can get through it then great.

I work as a frontend engineer and saw this q so I figured I'd chime in - Basically the workflow goes like - At the beginning of a sprint (basically your team is given a set of tasks and a deadline of like 2 weeks to a month). A lot of frontend engineering tasks have literally nothing to do with the UI, for example refreshing validation tokens when a user logs in from a new country. On the other hand, there's a lot of UI - related tasks (i.e make a signup form). In this case, in the description of your tasks you're usually provided a link to the designs drawn up by the UI team (we use software called figma). There we can interact with how stuff works (i.e on hover, on click, etc.) and we can leave notes with questions, or a lot of the time we can ask them in slack. Like (hey I noticed the corners on this button weren't rounded like the others, was that on purpose?)

Once I'm done developing the feature it has to first pass a high enough % of tests, and then it has to be approved by my manager, a peer, the designer, and the UX lead. Other than when my final work is being reviewed, I have 0 interaction with the UX team. They work more with marketing and business/product development and even the data team to figure out optimal user flows and whatnot. IDEK they're usually stiffs I try to avoid them.

Anyways go be an engineer its mucho dinero and much fun

^ I do door to door sales now which is a completely different field because I make more and its more fun to me. However I'm miles ahead of everyone else because of my engineering experience. Developing critical thinking skills extends to everything, and having an understanding of technology is literally beneficial everywhere. Even if you don't become an engineer the skill-set you develop is invaluable. Also @elder trail if you want internships/jobs in tech without college bootcamps are incredible and even offer money back guarantees. They also have partnerships with a ton of companies so you can literally get a job before you even graduate. IMO it's far more beneficial, cost-effective, and time-efficient than taking college classes unless your actually gonna go through a whole comp sci bachelor's.

SOLID?

https://en.wikipedia.org/wiki/SOLID

SOLID

In object-oriented computer programming, SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible, and maintainable. The principles are a subset of many principles promoted by American software engineer and instructor Robert C. Martin, first introduced in his 2000 paper Design Princip...

I want to make an agent that plays chess

hallow mist

Im still starting out with deep learning and most of my work has been in pytorch so I can't help you, sorry

tawny crest
#

tensorflow vs gym for the agent I dont think would make too much difference but im assuming youre making it all from scratch?

versed condor
versed condor

#

@versed condor I think Open AI-Gym would be better for your purpose as the framework since its more designed towards RL and training agents. Tensorflow could be used to optimize your agent and help it solve OpenAI Games. You would use OpenAI GYM as the environment and can use keras, theano or tensorflow to solve the computational algorithm and provide to the GYM env the algo.

#

I hope that makes sense...its like the crack of morning so I may..be making more sense in my head lol

#

There should be a gym-chess env already https://pypi.org/project/gym-chess/ you can take a look and build your skeleton around that..if that helps. Idk your DS experience so..im trying to not obfuscate my words

#

also if youre writing in python..I would look into cython to speed up your code.

Any programmers? Im taking java this semester and I'm having trouble fully understanding why Constuctors are useful. I'm very bad at grasping info through reading, so a summary and an example (of the full potential) is best for me to understand
edit:
what I understand so far: Its like making a variable with sub-variables for convenient access.

A way to understand it is imagine a class as a mold
An instance/object of that class is what you get when you pour something into that mold.

Each instance has it's own variables and methods where the initial values are taken from the mold but can be changed later on using getters and setters for example

Now what a constructor does is it pours into the mold so you can have specific initial values for your instances.
A default constructor does the same but you can't specify those initial values

Here is a concrete example:

public class Person {
    
    //instance variables
    private int age;
    private string name;

    //constructors

    Person() {}    //default constructor does not NEED to be explicitly coded in
    
    Person(int ageInput) {    //constructor that takes age only
        age = ageInput;    
    }

    Person(string nameInput) {    //constructor that takes name only
        name = nameInput;    
    }

    Person(int ageInput, string nameInput) {    //constructor that takes both age and name
        age = ageInput;
        name = nameInput;    
    }

}

Here we have multiple constructor each has a specific case use depending on whether we would like to have default or initial values for age and name

Hope this clarifies the whole thing

A constructor is mainly useful when variables are private such as age and name, otherwise there is no way to set those variables

#

Whereas if age or name were public, they could be set without the use of a constructor

# mystic crater how and what do you use to test things like html and css i never really got that

CSS and html are heavily integrated with javascript so they are tested as complete components. Tests are split into 3 types, unit, integration, and end-to-end (e2e). Unit tests test a specific function or component. For example an addTwoNumbers(x, y) function you might test that addTwoNumbers(2, 4) returns 6, and that addTwoNumbers(0, 'x') returns "please input 2 numbers".

Integration tests are for testing if your function/component fits in the systems its used in. For example you may have a collection of button, textbox, and tooltip components, and you test if they work in the context of the forms they are used in. So you might check that the parameters being passed between the components are right, or that the state of the global variables are correct at a given point, for example how many notifications a user has.

E2E testing is kind of where you test the 'html and css' or in reality, the actual user experience. These are usually long and slow, and actually render your browser on the screen, take control of your cursor and keyboard and literally go through the motions of making actions on your site. You might have one suite for all of the user login and registration and it just whips up a browser and spends 10 minutes making users and clicking random buttons and whatnot and you can actually watch it on the screen.

While most companies use all 3, usually unit tests are written the most, integration tests next, and e2e for only super important flows. In react (the most popular frontend framework) its usually more common to write integration tests most, unit tests second most, and e2e tests least. This is because react is all based on components, and because they are commonly packaged together to make the ui elements your users are interacting with, its better to test them as a collection anyways

It really depends on so many factors. Where you went to school, where are you looking to move, etc. Competitive programming is a great start but if you really want to stand out I suggest you get involved with an open source project or event. A lot of the big ones have programs for CS students where you can apply to get a mentor and work on a big feature for the next release. An example of one is the Django Summer of Code. Doing something like that or even just contributing to a project like django would do wonders for your resume
